OmniCC is an addon that adds text to items, spell and abilities that are on cooldown to indicate when they will
be ready to use. In other words: it turns all the standard analogue cooldowns into digital ones.
Anything should work with OmniCC, from the action bars to the inventory, from the standard interface to your favorite add-on.
Target Aura Durations
If you're playing on classic servers and missing cooldown counts for buffs and debuffs on the target unit frame, try ClassicAuraDurations.
